MEDIAN:
9 (middle)
MEAN:
(12 + 16 + 10 + 9 + 20 + 11 + 20) / 7 = 14
RANGE:
Highest value: 20
Lowest value: 9
Range: 20 - 9 = 11
INTERQUARTILE RANGE:
First quartile: 16 (It is between 12 and 10)
Third quartile: 11 (It is between 20 and 20)
Interquartile range: 16 - 11 = 5

we know that
<u>Alternate interior angles</u> are two interior angles which lie on different parallel lines and on opposite sides of a transversal. Alternate interior angles are congruent
see the attached figure with letters to better understand the problem
in this problem
the parallel lines are the lines a and b
the transversal line is the line c
so
the alternate interior angles are the Angle
and Angle 
m∠3=m∠6
therefore
<u>the answer is the option</u>
Angle
and Angle 
Answer:
24
Step-by-step explanation:
6 divided by 1/4 is equal to 6 times 4, which is 24. You multiply 6 by 4 because in fractional division, the second fraction, which is 1/4, is reciprocated to 4, as you 'flip' 1/4, giving you 4/1 = 4. Thus you multiply 6 by 4 and get 24.
Answer:

Step-by-step explanation:
stupid enough
y=mx+b

slope = 16-12/3-6
-4/3

plug in x and y
16=-4/3(3)+b
b=20
